Disclosed herein is a hearing instrument. The hearing instrument has improved corrosion protection. The hearing instrument can include a substrate. The hearing instrument can include a coating at least partially covering the substrate, the coating comprising at least two sets of alternating layers, a first layer of the alternating layers comprising a first material and a second layer of the alternating layers comprising a second material. The first material can include a dielectric material. The second material includes a hydrophobic material.

The present invention relates to a drip control device for a boom microphone for installation around the boom at a distance from the microphone. To improve the dripping off beads of perspiration, the drip control device as measured in the direction of the boom, has a length (L) and as measured in the direction perpendicular to the boom, a length (D) and that with respect to ratio of these dimensions, such a ratio L/D is greater than 1.

A device having one or more an acoustic modules. The acoustic module includes an acoustic element and a cavity that is acoustically coupled to the acoustic element. The module also includes a first conductive element that is configured to generate a first surface charge on a first region of an interior surface of the cavity. A second conductive element is configured to generate a second surface charge on a second region of the interior surface of the cavity. The first and second charge on the first and second regions of the interior surfaces of the cavity may be selectively applied to facilitate movement of a liquid held within the cavity.

A system includes a first audio device having a first microphone, first speaker, and first wireless interface, a second audio device having a second speaker and second wireless interface, and a computing device having a user interface. The user interface presents representations of the first and second audio devices. Upon receiving user input indicating a connection between the representations of the first and second audio devices, the computing device inquires whether a first or second mode should be used. Upon receiving user input confirming the first mode should be used, the computing device instructs the first audio device to send audio signals detected by the first microphone to the second audio device, which reproduces the audio signals. The first mode is selected based on whether the first and second audio devices is a loudspeaker or a headset.

A microphone cover system for includes a microphone to capture audible sounds. An odor enhancing unit is removably positioned on the microphone to inhibit moisture from contacting the microphone. The odor enhancing unit is comprised of a fluid permeable material to facilitate sound waves to pass therethrough to the microphone. Moreover, the odor enhancing unit emits a selected odor to enhance an odor associated with the microphone.
